Kaley Cuoco is opening up about what went wrong in her relationship with ex-husband Ryan Sweeting.
In the May issue of Cosmopolitan, the 32-year-old star of The Big Bang Theory reveals that after her first husband “completely changed” throughout the course of their relationship, she didn’t know whether she’d ever feel ready to walk down the aisle with somebody else again.
“I honestly thought I wouldn’t get married again. My ex ruined that word for me,” Cuoco, who is currently engaged to Karl Cook, tells Cosmopolitan in the magazine’s cover story.
Cuoco and the former tennis player got engaged in September 2013 after a whirlwind three month-long romance, but just 21 months later, the pair announced they were splitting up.
According to court documents obtained by PEOPLE at the time, Cuoco filed for divorce, citing irreconcilable differences.
“I married someone the first time who completely changed,” Cuoco tells Cosmopolitan. “The person I ended up with was not the person I originally met. And that wasn’t my fault — that was his.”
Despite getting burned, Cuoco says the heartbreak ultimately led her to Cook, whom the 32-year-old recently described to PEOPLE as “my perfect match.”
“I knew how much I had to give and how much I wanted to receive. I knew I just had to be patient…I had to go through a lot of things, but it brought me to Karl,” she tells Cosmopolitan.
